Don't miss Sunday's supermoon -- with meteors!

This weekend packs a one-two punch for sky watchers. Sunday night is a supermoon, when the full moon coincides with the moon's closest approach to the Earth during its elliptical orbit. It also marks the start of the Perseid meteor shower.

Astronomers call them perigee full moons, as perigee means "near Earth." Still, the term doesn't quite fit with the glory of a rising supermoon, so even science sites have started using it.

The light of the supermoon will have the unfortunate effect of making the annual return of the Perseid meteor shower less visible, though.
